Narrowband IoT

Is Your Mobile Network Ready for the Internet of Things?

Be Ready for the Internet of Things

IoT will enable billions of smart devices to connect to mobile networks via narrowband signals. At the same time, mobile networks must continue to support high-bandwidth applications—such as video streaming—that use wideband signals. Network operators need to manage these different types of connections while maintaining the required quality of experience for each, and minimizing the need to invest in new equipment.

Narrowband IoT Testing: What You Need to Know

Get the VIAVI Advantage

VIAVI has developed software-based NB-IoT testing—the first of its kind in the industry—available as a license on CellAdvisor handheld instruments. This further enhances CellAdvisor as a comprehensive RF test solution, offering RF over CPRI and BBU emulation in addition to LTE testing and automated interference hunting to help maximize efficiency of technicians while visiting cell sites.

With NB-IoT support, CellAdvisor:

Measures the interference and performance impact the NB-IoT signal may have on the LTE wideband signal

Confirms whether the signal has the reach and coverage required to serve the number of devices in the assigned geographic area

Provides comprehensive analysis, including signal power levels, digital demodulation analysis and interference analysis down to the single physical Resource Block (PRB)

These detailed measurements provide a full picture of how well the network is operating in terms of performance, coverage and data traffic capacity, while identifying potential issues related to interference or intermodulation that need to be resolved.
